I haven't used that system yet, but we did go and buy a Poulan Pro blower/vac the other day... it works well, but a couple of things to remember...

- this thing IS powerful enough to pick up small rocks...
- even though it's cold outside and the heat from the (guarded) muffler feels really good, keep it away from your body... it WILL burn your clothes...
- if you're using the bag while you're using the vac, remember to ZIP IT UP.... otherwise, you may as well not have it on at all.

We're planning on trying something like that attachment sometime.... hopefully this time next year we'll have one of these bad boys.... (not necessarily this brand)
